Hairy week it is. An obscure word?
Jazey ; noun ... Question: what's a jazey?

more commonly(?), jasey.

This websters gives one source for jazey as a wig and one for it as a bob wig.

I ought to take a count sometime and see how many websters/webster's there are now.

Right, I had it from the 1785 Vulgar Tongue and as OneLook did not give it and the Worthless did not give I thought it might be hard to find. My Webster I forgot to check and that's dumb as it often has the one thing no one else has.

Jazey A wig; a corruption of Jersey, and so called because they are made of Jersey flax and fine wool. Source: Brewer's Dictionary. Slang in 1811 JAZEY. A bob wig.

My Webster is: Webster's Online Dictionary with Multilingual Thesaurus Translation. I like it.

(not knowing it also exits as 'jasey').

as to counting Websters, good luck with that!

Dictionaries, helpful or ?
jasey
a wig, esp. one made of worsted.

worsted
1. firmly twisted yarn or thread spun from combed, stapled wool fibers of the same length, for weaving, knitting, etc.
2. wool cloth woven from such yarns, having a hard, smooth surface and no nap.

So is a jasey made of yarn, thread or cloth?

Nice jasey - you look like Raggedy Ann.

Great!
add to this:
and so called because they are made of Jersey flax and fine wool.

Flax? Ah yes, good fiber in the event a jazey is accidentally ingested during a windstorm.
